Establishments like banks and businesses are always under the scanner of unscrupulous eyes, raising an ever-increasing threat to their security. As technology evolves, break-in attempts are also getting more sophisticated with burglars using advanced state-of-the-art tools to attempt their brazen heists. Needless to say, the first step is to fortify the first point of attack - the Strong Room Door.

Godrej Strong Room Doors combine unique Double Duty Barrier (DDB) material and Torch & Drill (TDR) Matrix to offer superior resistance, not only against common hand tools, picking tools and impact tools, but also against oxyacetylene torches.

Strong Room Door Classes:

  • Strong Room Door Class I or C: Consists of a composite slab of thickness 18mm, made of a special layer of flame and arc-resistant alloy that protects against fire, power drilling, oxy acetylene torch and arc cutting. It is further fortified with a composite 62mm layer of Godrej Double Duty Barrier (DDB).
  • Strong Room Door Class II or B: Consists of a 25mm slab of Torch and Drill Matrix Slab (TDR), to protect it from attacks by impact tools, drills, oxy acetylene torch and arc cutting. It is further fortified with a 65mm layer of Godrej Duty Barrier ((DDB). Door comes along with clenching mechanism.
